- Java

import java.util.Scanner;

class Solution {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int a = sc.nextInt();
        int b = sc.nextInt();

        for(int i=0;i<b;i++){
            for(int j=0;j<a;j++)
                System.out.print("*");
            System.out.println();
        }
    }
}

 

- Ruby

n, m = gets.chomp.split(' ').map(&:to_i)
m.times{
    n.times{print("*")}
    print("\n")
}
